Average kinetic energy per molecule of He gas at temperature T, is E. Molar constant of gas is R. Calculate Avogadro’s number.

Calculate the kinetic energy of per gm molecule of He gas at 27^@C .

Write down the expansion for pressure of an ideal gas according to kinetic theory of gases. Given that at absolute temperature T, the average kinetic energy of a molecule of an ideal gas is 3/2(R/N)T , where R is the universal gas constant and N is the Avogadro number Determine the equation for ideal gases from his.

If the average kinetic energy of the molecules of a certain mass of a gas decreases, then

Prove that the average kinetic energy of a molecule of an ideal gas is direcly proportional to the absolute temperature of the gas.

Prove that c_(rms)=sqrt((2E)/(M)) [E=total kinetic energy of the molecules of 1 mol of a gas, M=molar mass of the gas, c_(rms)= root mean square velocity of gas molecule].

The dimension of molar gas constant (R) is -

For an ideal gas, C_(V)=(3)/(2)R . (a) What will be the change in internal energy (DeltaU) of 1 mole of an ideal gas if its temperature is increased by 4K at constant volume ? What would be DeltaU if the temperature of this gas is increased by the same amount of constant pressure? keeping pressure constant if the temperature of that same amount of gas is increased by 4K then what will be the change in internal energy (DeltaU) of that gas? (c) give reason for different values of DeltaU and DeltaH ?

The average kinetic energy of a molecule in a gas at STP is 5.6 times 10^-14erg . Find out the number of molecules per volume of the gas Given, density of mercury =13.6 g.cm^-3 .

"The total kinetic energy of the molecules in an ideal gas with a volume V at pressure P and temperature T is equal to the total kinetic energy of the molecules present in the same volume of another ideal gas at the same pressure and at temperature 2T"-Justify the statement.

Use kinetic theory of gases to show that the average kinetic energy of a molecule of an ideal gas is directly proportional to the absolute temperature of the gas.
